The couple – who have been together since meeting on the set of ‘Mr. and Mrs. Smith’ in 2005 – have finally given into the pleas of their older children, Maddox, eight, Pax, six, Zahara, five, and three-year-old Shiloh and agreed to tie the knot.

A source close to the couple – who also have 22-month-old twins Knox and Vivienne – told America’s OK! magazine: “First it was Maddox, who has begged his parents to tie the knot for years. “Lately, Shiloh and Zahara have been chiming in, and Pax thinks it would just be the coolest thing ever to be a ring bearer.”

Angelina, 34, has previously admitted she and 46-year-old Brad are expecting the children to eventually start questioning why they had never got married. She said: "Usually people fall in love and everything revolves around the ritual of marriage, children are an afterthought. We did everything backwards. "But sooner or later it will be the kids who ask us to get married. You know, they see films and start asking questions. Such as, ‘Why are Shrek and his love Fiona married and you’re not?’ ”
